amitraz is one of the pesticides which is used in a vast area for controlling of the common pistachio psyllid, agonoscena pistaciae (hem.: aphalaridae). in this study the synergistic effect of piperonyl butoxide (pbo) on the toxicity of amitraz on adults of rafsanjan population of common pistachio psyllid was evaluated by residual contact vial (rcv) in laboratory conditions. the results showed ...

insect natural enemies selected for such specific traits as faster developmental times, longer survivor, increased fecundity, and larger body size might be considered during production of biological control agents in certain situations. for instance, traits related to developmental rates may be selected for, if genetically based variation exists within temperature-dependent responses. hippodami...

Pear psylla, Cacopsylla pyricola (Foerster) (Homoptera: Psyllidae), is one of the key insect pests in North American pear production. In some growing areas, more than 50% of dollars spent to control arthropod pests in commercial pear are directed specifically at controlling this species. Control measures require accurate and timely information about dispersal, onset of egg-laying in spring, den...

Different methods have been applied to recycle pistachio’s green hulls, the most important of which are siloing and drying pistachio hulls (using industrial dryers). In both methods, hulls should lose their initial moisture content, which constitutes a considerable portion of their weight. The high moisture content takes more time and energy during the drying process. The initial dewateringof h...

Pear psylla, Cacopsylla pyricola (Förster) (Homoptera: Psyllidae), is a major pest of commercial pears in North America and Europe. Olfactometer trials have shown that males of both the summer and winter morphotype are attracted to female-infested host material. Additional work with the summer morphotype has shown that males are attracted to females even in the absence of the host plant, which ...

in this study, 99 isolates of rhizoctonia were recovered from root and crown samples of pistachio seedlings, and soil samples were collected from major pistachio orchards in kerman province. results revealed that 96 isolates were multinucleate and 3 binucleate. mnr belonged to ­ag-4. results of the pathogenicity tests carried out in the greenhouse, using pistachio isolates, revealed that all mn...

Pistachio as a strategic product has a particular position among Iranian productions and is one of the most important non-oil exports after carpet. In this study, after primary processing such as dehulling, washing, drying and roasting, pistachio nuts were packed in four different atmospheres including N2, CO2, vacuum and ambient air. Storage temperatures were 20 C and 40 C for a 12 month perio...
